Is predicted to encode a protein with the following domains: P-loop containing nucleoside triphosphate hydrolase; Helicase conserved C-terminal domain; and Helicase, C-terminal. Is an ortholog of C. elegans F53H4.6;
csb-1; and
pqn-15. In C. elegans,
csb-1 is involved in UV protection and transcription-coupled nucleotide-excision repair.
